ANTIFRICTION-BEARING FOR lRAIYVATt'-CARS.

Application file fuy 24. 1913.

To 1H whom t 11ml/ concern:

lle it known that l, ARNOLD A. V1-noni., a citizen of the United States, and a resident of Chicago` in the countvv of Cook and State pf illinois. have invented certain new and useful Improvements in ntit'rictioniearings for Railvvavlars; and l do hereb v declare that the `followingA is a full. clear. and exact description thereof. reference being' had to the accompalrviug drawings` and to the letters of reference marked thereon, which foi-1n a part of this specification.

This invention relates to an improvement in antit'riction bearings. and is shown herein as applied tor use in connection with a side bearing for railwa)v cars. The inven- Vtion consists of the matters hereinafter described and more particularl)V pointed out in the appended claims.

The improved bearing'. as shown herein. is ot' that type which includes a carrier or casing and an antit'rietion element provided with trunnions by means ot' which it is suspended within the carrier, Said carrier havinteT tracks or runways on which the trunnions ot the antit'iiction element roll when the antit'riction element is released from load. (lne objectionable feature heretofore inherent in this type ot' bearingy is that after. in the transmission oi' the load. the antitric` tion element has traveled in either direction trom its normal central position to the limit ot its movement in the easing` anyv further movement of the bearing as a whole will cause the antitriction element to grind against the` end wall of the casing and the top wear-plate with resultant added triction, grinding noise and wear ot' the antifrictiony element.

'lhe object of the present invention is to provide an antifriction bearing which is without this objectionable feature.

ln they drawings:-l"ignre l is\a view rc])resentingV a( longitudinal central section through my improved hearing' with the a tit'riction element shown in the position which it occupies when transmitting load, Fig'. l) is a similar view. showingr the position otl the antitriction element as it appears when transmitting load after it has reached Specification of Letters Patent.

Fig. is a view representing a like, section taken in a plane indicated by tlie .lineilM-llat Fig. 1. Fig. 5 a view rei'iresenting a hariaoiM tal section through Fig. l in a plane in cated b v the line 5 -5 ot Fig. 1.

Referring now to that embodiment of mjy' invention shown in the drawingsfwl@l indicates the casing. which is an oblong, rectangular shell, open top and bottoni, and provided with flanges 11, 11 at the'top for attachment to the body bolster 12 of a railroad car. The casing, as shown herein. is formed with its top vplane inclined to the horizontal. to coincide with the inclined end ot' the bodyY bolster to which it is attached.

'13, 13 indicate the side walls of the cas ing and 1l. 1l the end walls thereof,

ll indicates a filler block which closes the top oi the casing,r and contines the antitriction element therein. Said filler block rests at its ends on transverse horizontal shoulders 15. 15 on the end walls 1l, 14 ot the casing. I

1T indicates an antitriction element hav ing trunnions 17a. 17a which bear upon in- 'turned flanges 18, 1S tornied at the hottom edges ot the side walls 1B of the casing. Said flanges constitute tracks or rails and are inclined downwardly from each direc tion toward the central normal position ot' the antifriction element, which is caused by gravity to roll down said rails on its trunnions in a familiar manner, when it is released from load.

The filler block 1G is provided with depending side flanges 16X, 16X which are located adjacent to the side walls 13, 13 of the `asing. Said flanges provide upper rails 19. 19 which are opposed to the lower rails 18, 18 and act with said lower rails and the side walls ot`- the casingr to form longitudinally extending channels to @online the trnnnions ot' the anti-.friction element.

1in the filler block tianges 16X, bevond the ends of the rails 18, there are provided seniicircular hearing pockets 2.2, Said seminntifriction elementthrough said fixed bearings when said nniirii'ziinn element' :it they ands of its path of trawl.
